Are 737 Max Planes Still Flying? | Your Current Guide

Yes, Boeing 737 MAX aircraft are actively flying again with airlines globally after extensive safety reviews and software updates.

Navigating air travel often brings questions about the aircraft we fly, and the Boeing 737 MAX has certainly been a topic of discussion for many travelers. It’s completely natural to seek clarity on its current status, especially given its history. Understanding the facts helps us all travel with greater peace of mind and make informed choices.

The Grounding and Recertification Process

The 737 MAX aircraft family faced a global grounding in March 2019 following two tragic accidents involving Lion Air Flight 610 and Ethiopian Airlines Flight 302. These incidents, occurring within five months of each other, were linked to a flight control system known as the Maneuvering Characteristics Augmentation System (MCAS).

Initial Incidents and Global Grounding

Investigations revealed that erroneous sensor readings triggered the MCAS system repeatedly, pushing the aircraft’s nose down. Pilots, unfamiliar with this new automated system and its behavior, struggled to regain control. This led aviation authorities worldwide, including the Federal Aviation Administration (FAA) in the United States, to issue emergency orders grounding the entire 737 MAX fleet for safety reasons.

Rigorous Review and Software Updates

During the grounding, Boeing worked extensively on software updates for the MCAS system. This involved modifying the system to rely on inputs from two angle-of-attack sensors instead of one, and to only activate once per event. Furthermore, pilots now have the ability to override the system more easily. The FAA, as the primary aviation safety authority in the United States, rigorously oversees aircraft certification and operational standards, playing a central role in this review.

The recertification process was comprehensive, involving thousands of hours of testing, simulator evaluations, and regulatory scrutiny from multiple international aviation bodies. Independent investigations into aviation incidents, including those involving the 737 MAX, are conducted by the NTSB to identify root causes and issue safety recommendations.

When Did the 737 MAX Return to Service?

The return to service for the 737 MAX was a phased process, beginning with the FAA lifting its grounding order in November 2020. This decision followed nearly two years of safety reviews, software enhancements, and new pilot training requirements.

Airlines in the United States began reintroducing the aircraft into their schedules shortly after the FAA’s approval. American Airlines operated the first commercial passenger flight with the updated 737 MAX in the US on December 29, 2020. Other major carriers followed suit in the subsequent months.

Internationally, other major aviation regulators like the European Union Aviation Safety Agency (EASA) and Transport Canada also conducted their own independent reviews before granting approval for the MAX to return to their respective airspaces and airlines. This staggered return ensured that each regulatory body was satisfied with the safety enhancements.

What Changed on the 737 MAX?

The period of grounding led to significant modifications and enhancements to the 737 MAX, addressing the issues identified in the accident investigations. These changes focused primarily on the flight control systems and pilot training protocols.

• MCAS Software Update: The most critical change involved a comprehensive update to the MCAS software. It now compares data from two angle-of-attack sensors, and if they disagree by a certain threshold, MCAS is deactivated. It also limits MCAS activation to a single instance per event and provides pilots with an easier way to override the system.
• Enhanced Pilot Training: All pilots flying the 737 MAX underwent mandatory, updated training. This included specific simulator training on the MCAS system, its operation, and recovery procedures in various scenarios. This ensures pilots are fully prepared for any unusual flight conditions.
• Additional System Checks: Boeing and airlines implemented additional maintenance and pre-flight checks to verify the integrity of the flight control systems and sensors before each flight. These checks add another layer of safety assurance.
• Wiring Modifications: While not directly related to the MCAS incidents, Boeing also addressed potential wiring issues identified during the review process to prevent future electrical faults.

Identifying a 737 MAX on Your Flight

Knowing the aircraft type for your flight is straightforward and can be done at various stages of your travel planning. Airlines typically provide this information, and several online tools are available for verification.

1. During Booking: When you book a flight online, most airline websites display the aircraft type for each segment. Look for details next to the flight number or in the flight information section.
2. Airline App or Website: After booking, you can check your reservation details on the airline’s official app or website. The aircraft type is usually listed there and is subject to change, though less frequently closer to departure.
3. Flight Tracking Websites/Apps: Services like FlightAware or FlightRadar24 allow you to track specific flights and view the aircraft type scheduled for that route. These are particularly useful for real-time updates.

The 737 MAX comes in several variants, primarily the MAX 8, MAX 9, and MAX 10 (which is still undergoing certification). While they share common characteristics, their passenger capacities and ranges differ slightly.
